Installation Distances
According to the EN 1366-2 standard, the minimum distance from the wall or ceiling to the damper body is 75 mm.
For multiple crossings through a fire resistive wall, the minimum distance between two damper bodies is 200 mm.
This applies for distances between the damper body and a nearby foreign object crossing the fire resistive wall.
Damper clearances vary from the type of mechanism and their rotation (see Fig. 3).
